Johns Manville R-30 Unfaced Fiberglass Insulation Roll 15 in. x 25 ft.

JM Unfaced Formaldehyde-free fiberglass insulation offers R-values ranging from R-11 to R-38 and provides effective thermal and noise control. Our R-30 unfaced rolls are for easy installation in 16 in. on center 2 in. x 10 in. attics and ceilings. Can be added to existing attic insulation. Unfaced rolls are great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces, and are available for wood or steel stud framing. They can be used with a separate vapor retarder when moisture control is required. JM insulation is made from bonded glass fibers that are dimensionally stable and will not slump within the cavity, settle or break down during normal applications.
